NEWS for 1.3 MELT plugin for GCC 5 & GCC 6
[[may XX, 2016]]
Bug fixes
=========
Rare garbage collection bug fixed (noticed with GCC 5).
Language features
=================
No significant new language feature.
Runtime features
================
We did keep compatibility with GCC 5 & GCC 6.
Since gengtype does not admit conditionals (see messages following
https://gcc.gnu.org/ml/gcc/2016-02/msg00156.html ...) we had to hack
our build system. The MELT plugin now use some melt-runtypes.h
symlink to a version specific file, which has typedef-s like
typedef gimple* melt_gimpleptr_t; // gimple is now a struct
